Sorry for my English I will do my best to explain this. The carbs of this Honda Magna have a knob in the middle of the carbs. It is for idle adjust, but is the problem is bigger you have to clean the carbs, check the jets and diaphragms is better if you can use an air compressor or maybe a vacuum sincronizer.
this is a carb unit there should be a nice flow of fuel but pressure is not possible because this has no fuelpump
Golem in the Gears was created in 1986-02.
